1. Definitions
1.1 An annuity is a lump sum of money which is invested, for the purpose of securing a constant income for a specified period.
1.2 Generally, the return is guaranteed for a period of time at a fixed rate. The risk of being able to grow the initial investment in order to pay the fixed income, is taken by the investment company.
1.3 The advantages to the investor, are usually in the favorable tax benefit that accrues, as well as the guaranteed income.
1.4 The annuity increases by its interest return and pays out a fixed sum for the duration of the specified period. At the end of the specified duration, the funds are depleted and the investment is terminated.
